本文介绍了一种用于相位调制连续波（PMCW）雷达系统的15 Gb/s集成基带伪随机噪声发生器。通过将外码（OC）慢时间调制到伪随机二进制序列（PRBS）上，该电路使MIMO和联合雷达通信（RadCom）系统能够在D波段及以上。据作者所知，这一点尚未得到证明。电路功耗7.2mW，面积400 × 530 μm2。它是在22 nm全耗尽绝缘体上硅（FDSOI）技术中实现的，其中PRBS由真单相时钟（TSPC）触发器形成的移位寄存器产生。
This paper presents an integrated baseband pseudo-random noise generator at 15 Gb/s for phase-modulated continuous-wave (PMCW) radar systems. Through slow-time modulating an outer code (OC) onto a pseudo-random binary sequence (PRBS), the circuit enables MIMO and joint radar-communication (RadCom) systems in the D-Band and above. To the best of the authors' knowledge, this has not yet been demonstrated. The mixed-signal circuit consumes 7.2 mW in power and 400 × 530 μm2 in area. It was realized in a 22 nm fully-depleted silicon on insulator (FDSOI) technology, where the PRBS is generated by a shift register formed by true single-phase-clock (TSPC) flip-flops.
